PULVERIZER.

To all whom it may concern:

Be it known that I, CHARLES A. Barns, a citizen of the United States, residing at Vernon I-lill in the county of Halifax and State of Virginia, have invented certain new and useful Improvements in Pulverizers, of which the following is a specification, ref erence being had therein to the accompanying drawing.

This invention relates to pulverizers and has for its objects the production of an efficient attachment for a plow which may be used for pulverizing the ground and removing large lumps therefrom at the time of giving the ground its final finish attention.

A still further object of the invention is the production of an efficient means for at taching the pulverizer to the frame of the plow or beam thereof whereby the pulverizing blades may be adjusted to the desired angle to accommodate the ground over which the pulverizer is being moved.

With the above and other objects in view this invention consists of certain novel combinations constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing: Figure 1 is a perspective view of the pulverizcr applied to the ordinary plow beam. Fig. 2 is a side elevation of the pulverizer detached from the plow beam. Fig. 3 is a detail perspective of one of the pulverizing blades. Fig. t is a top plan view of the pulverizing blade. Fig. 5 is a detail perspective of one of the braces used in connection with the pulverizing blade. Fig. 6 is a modified form of the pulverizing blade which is used in connection with 'flat ground.

By referring to the drawing it will be seen that 1 designates the plow beam. to which the pulverizer is adapted to be at tached. The pulverizer comprises a vertical standard 2 which standard constitutes a pair of parallel arms fitting upon opposite sides of the plow beam 1. The lower end of the standard 2 is flattened to form a head 3 which head is bent substantially at right angles to the standard 2 so as to extend in an upward position relative thereto. A bracing bar 4: is connected between the Specification of Letters Patent.

parallel arms of the standard 2 by having its downwardly extending portion 5 secured between the arms by means of a bolt- (5 which bolt his in one of the adjusting a ertures 7 ftn'n'ied in the standard 2. T 1e rear end of the brace 41; is provided with a laterally extending foot 8 through which a bolt 9 passes for attaching the same to the rear end of the plow beam 1. It will be seen that this brace t will constitute an ellicient means for rigidly holding the standard 2 in its correct position. The parallel arms of the standard 2 fit upon each side of the beam 1 as previously described and as clearly illustrated in Fig. 1 and are firmly held in engagementwith the beam by means of the securing bolts 10.

A pair of pulverizing bars or blades 11 are pivotally secured to the under face of the upwardly projecting head 3 of the standard 2 and are preferably formed as illustrated in Figs. 1, 2 and 3 by having the body thereof slightly curved upwardly and outwardly toward the center and having the extreme end 12' thereof twisted to extend inwardly and lie in a vertical plane to constitute a means for packing the earth upon the hills which have been previously formed in the fields. It should be understood that these blades 11 are shaped to conform to the hills previously formed in the field so as to pulverize the earth and yet prevent the regular form of the hill from being disturbed. It of course, should be understood that there is a pulverizing blade 11 upon each side of the standard 2 so as two rows of hills may be pulverized at the same time and also a greater space of the field acted upon by means of the pulverizing blades 11.

Diagonally extendingreinforcing braces 12 are connected to the pulverizing blades 11 intermediate the ends thereof by means of pivot pins 13 and these diagonally extending braces 12 are provided with rearwardly extending ends 14: which ends are secured to the rear end of the beam 1 for constituting an efficient means for bracing the pulverizing blades 11. The rearwarclly extending blades 14 01": the braces 12 are provided with a plurality of apertures 15 whereby the braces 12 maybe adjusted forwardly so as to regulate the adjustment of the pulverizing blades 11. It should be understood that by moving the braces 12 forward the rear ends of the pulverizing blades 11 may be spread farther apart and by drawin the braces 12 rearwardly the rear ends of the pulverizing blades 11 may be drawn closer together.

In Fig. 6 there is shown an embodiment of the invention wherein a modified form of pulverizer blade 16 is illustrated having an oft-set end 17 which is adapted to engage the head 3 of the standard 2. The pulverizing blade 16 which comprises a long fiat straight body is also provided at the rear end thereof with a right angularly twisted and inwardly bent tongue 18 which is adapted to press any loose earth which might be left in the rear of the pulverizer upon the surface.

From the foregoing description it will be seen that a very simple and eiiicient pulverizer has been produced which may be attached either to the ordinary plow beam or to the commonly used gang plow and still perform the desired function, owing to the fact that the same may be readily adjusted to different width supporting means. It should be further understood that the present invention may be modified as to its detail mechanical construction without departing from the spirit of the invention and that the same may be adapted to any form of machine which may be produced for the purpose of pulverizing or treating the land in any manner.

Having thus described the invention what is claimed as new, is

1. pulverizer comprising a standard, means for bracing said standard, said standard provided with a forwardly extending end, a plurality of pulverizing blades pivotally secured to said forwardly extending end, said blades provided with inwardly turned shoes at their rear ends and adapted to pack the earth over the hills formed in the field, and rearwardly extending braces secured to said pulverizing blades for holding the same in a set position.

2. A pulverizer comprising a standard provided with a plurality of parallel arms, said arms provided with a plurality of apertures formed thereon, said standard provided with a forwardly extending end, a brace engaging said standard and provided with a plurality of apertures, means passing through said apertures in said brace and standard for holding said brace in an adjusted position, a plurality of pulverizing blades secured to said head and having upwardly bowed portions near the center thereof, said blades provided with inwardly extending twisted rear ends, and inwardly extending braces engaging said pulverizing blades.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
